Hyperspectral imaging for the detection of ovarian cancer metastases

Design & evaluation of a new intraocular illumination system for vitreoretinal surgery: the RingLight

Throughout history, different intraocular illumination methods for vitreoretinal surgery have been used and the most common limitations to the state-of-the-art intraocular illumination methods are the glare and reflections created by the illumination device and the relatively small illuminated area. A way to tackle these limitations could be by...

Design of a combined optical and structural bone phantom: Concept validation and design tool

Introduction: Although being the most advanced spinal stabilization method, pedicle screw fixation has an increased number of complications compared to other surgical procedures, due to the complex spinal anatomy, large inter-patient anatomical variability, and the highly vulnerable surrounding tissue of the spine. Screw fixation strength can be...

The design of a brain and tumor phantom: Focused on mimicking the stiffness of the brain and glioblastoma multiforme tumor tissue

Glioblastoma multiforme tumors (GBM) are the most frequent and aggressive brain tumor type and have a very low survival rate. In order to improve the patient’s outcome for a patient suffering from GBM the production of brain phantoms can be of great help. A brain phantom can be used for multiple purposes, such as neurological planning, training...

3D Robotic Ultrasound System: A 3D Volumetric Ultrasound Imaging System using a CMUT Phased Array and a Robotic Arm

Diagnostic imaging is a fundamental requirement for the effective treatment of about 25 % of patients globally. Ultrasound imaging is considered the safest, least expensive and most convenient diagnostic imaging modality. Its widespread adoption has been in the area of 2D imaging. However, the accuracy of diagnosis with 2D ultrasound imaging is...

Intraoperative remaining surgery duration estimation to improve operating room scheduling: The creation and evaluation of an estimation system

One of the main elements for creating an optimal operating room schedule is an accurate surgery duration estimation. Currently, this estimation is only done preoperatively. However, multiple factors during the surgery itself could influence the duration, for example bleeding. Literature showed the possibility of intraoperatively estimating a...

Applicability of video-based workflow monitoring of interventional cardiac procedures performed in Reinier de Graaf Hospital: Identifying variability of procedure times and associating factors

In hospitals, the duration of surgical procedures is susceptible to a number a factors resulting in varying procedure durations of the same procedure. When these procedure times deviate from the predicted surgical duration, scheduling conflicts arise, leading to patient discomfort and inefficient use of hospital resources. Considering the aging...

Objective Image Quality Assessment and Comparison of Ultrasound Probes: Research to Application of Trans-Balloon, Miniaturized TEE in Atrial Ablation Procedures

Atrial Fibrillation (AF) is a common type of arrhythmia, characterized by rapid and irregular contraction of the atria. Irregular contraction of the atria is caused by erroneous electrical activation, originating from the tissue around the Pulmonary Veins (PV) in the Left Atrium (LA). Catheter-based treatment of AF includes ablation of the...

The Design of an Anthropomorphic Brain Phantom: Containing Ventricles

Brain, outside the body, will decay quickly, causing ex vivo studies to be difficult. Having a phantom model has a great beneficial value for numerous reasons. Phantoms are, among others, used in research centres, to validate new equipment, to develop biomechanical models or to test new treatment methods. They are representations of organs or...
